I be use for other purposes.

One object of my present invention is to provide a neat comfortable bathing sandal of novel construction.

Another important object of my invention u is to provide a rugged inexpensive general utility slipper which will not deteriorate, if subjected to moisture, and which'is for thls reason especially adapted for use as a bathin shoe.

till another important object of my mvention is to provide a bathing sandal havm a moulded cellular rubber sole and an a band, firmly secured thereto by being moulded into the sole.

Among the other objects and advantages of my invention is the novel method of making a slip r of moulded cellular rubber; the novel met od of attaching the arch band to the sole of the slipper; and the provision of novel means for preventing the shoe from slippin on wet surfaces and of 'improved means or holding the slipper firmly to the foot of a wearer toprevent the shoe from wobbling, and thus improve its wearing characteristics.

These and numerous other objects of the invention will be apparent as it is more fully understood from the followin description which, taken in connection wit the accomanying drawings, discloses a preferred embodiment of my invention.

Referring to the drawings: Figure 1 1s a perspective view, taken from above, illustrating a slipper embodying my invention; Figure 2 1s a in the drawings a slipper having certain fea# perspective view, taken from below, to further illustrate the slipper showni tures of advantage which adapt it particularlyforuseasaba oe.

The shoe 11 comprises a sole indicated generally at 13, which isa foot retaining means comprising in the illustrated embodiment, an arch retaining strap 15. The strap 15 may be conveniently formed of any suitable woven material, such as canvas. The sole 13 comprlses a sole strip 17, which may be formed from a strip of canvas and a moulded sole 19. I may form the sole of suitable mouldable or composite material, but prefer to utiliz e sponge rubber for this purpose, since th1s material may be readily moulded, and provides a highlfy resilient and extremely comfortable sole or the slipper.

The sole strip 17 may be imp with rubbery material to facilitate the adhesion of the rubber sole which is mounted directly to the sole strip. The solo 19 comprises a heel pad 21, a toe pad 23 and an interconnecting relatively narrow portion 25.

In order to improve the walking characters of the slipper, I provide means for preventing the sole from slipping and for securlng the slipper more firmly to the foot of a wearer. In order to furnish support for the arch of a wearers foot, I provide a. plurality of longitudinaly lins or flanges 27, whlch are formed integrally with the sole in the lower surface of the narrow connecting portion25 of the sole. These fins extend between the forward edge of the heel portion 21 and the rear of the toe portion 23, and in walking when the sole 19 is flexed, these flanges or fins make contact with the pavement and support the arch of the wearer. These fins also tend to off-set the tendency of the slipper to slip laterally.

T o prevent lo 'tudinal slipping I form an lntegral mtu rant band 31 of rubber acrossthesoeattherearofthetoe rtion 23, and .providing the surface of this protuberance with a pluraliliotf lateral grooves 29. It will be apparent the grooves and ridges in the surface of the lateral protuberance 31 y.will be preed against the pavement when the slipper is worn and will thus prevent the shoe from slipping back and forth upon the pavement.

I have also provided lateral upstandin anges 33 at the sides of the toe portion and extending from the forward edge of the arch strap 15 to points spaced rearwardly of the front end of the toe portion 23. These flanges are formed integrally of the sole 19 durlng the sole moulding operation and engage the sides of the foot of a wearer, and thus prevent the slipper from wobbling and thus improve the walkin characteristlcs of the slipper because the s oe itself is easier to steer.

The arch stra is tapered forwardly to fit the foot and is ormed of a band of suitable woven material which encircles the sole strip 17 extending between the sole strip and moulded sole 19 at the instep of the shoe, 'so that the arch strap is moulded into the sole. In addition, the arch strap is secured to the sole strip by means of rivets 35. The shoe is finished by securing an inner sole 37, which may be formed conveniently from a strip offine canvas, or similar woven material, across the upper surface of the sole 13.'

Among the advantages inherent in the shoe which I have hereinbefore described are the advantages arising from the side supports, which extend forwardly of the arch retaining strap and engage the sides of the foot to thereby prevent the foot from wobbling in the shoe; and to permit easy walking, the non-slipping properties of the shoe because of the grooves 29 1n the resilient protuberance at the rear of the toe portion 23, the arch supporting fins 27 and the inherent comfort of the shoe because of the cushioning features of the cellular rubber. These advantages are of course in addition to those arising through the inexpensive nature of the moulded shoe, the process of making same, the sightly appearance of the product and its utility.

It is thought that the invention and numerous of its attendant advantages will be understood from the foregoing description and it is obvious that numerous changes may be made in the form, construction and arrangement of the various parts without departing from the spirit and scope of the invention or sacrificing any of its material advantages, the form herem described being al preferred embodiment of the invention.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A sandal comprising a flexible sole having longitudinal arch supporting flanges and an arch retaining strap forming with the sole a tapered opening into which the foot of the wearer may be inserted whereby when the foot is pressed into the tapered socket the flexible sole will be drawn up against the arch of the wearer to support the same.

2. A slipper comprising a sole member comprising a sole strip and a layer of resilient material and an arch retaining strap, having its ends riveted to the sole strip and embedded in the resilient material.
